摘要: 为了研究河北省大风灾害特征及其危险性区划,笔者利用河北省1983—2011 年各地区县市统计年鉴、大风灾情数据以及气象站风速数据,基于灾度和危险度2 个指标,对致灾性大风时空分布、大风灾害特征和危险度进行研究。结果表明,河北省致灾性大风地理分布主要有2 个中心,分别位于冀北高原张家口地区和沿海沧州地区,春季频率最高;河北省各地区均有风灾事件发生,受灾情况属于轻灾,即为县级为主管单位进行救灾;结合致灾因子(致灾指数)和承灾体(风灾承灾指数),利用风灾危险度评价模 型,得出河北省存在14 个风灾极重度危险地区。风灾危险性与致灾因子分布不一致,表明危险性评价需要结合承灾体因素;在常用风灾危险性Dx的评价中,需要结合更多与风灾相关的承灾体参数,提高承灾体部分对危险性影响的比重。

Abstract: To analyze the wind disaster characteristics and hazard regionalization in Hebei Province, temporalspatial variation of gale frequency, wind disaster degree and risk assessment were studied based on the data from statistical yearbook, wind disaster database and wind speed data from weather stations of Hebei Province in 1983- 2011. The results showed that: there were 2 centers of wind geographic distribution in Hebei Province, which were located in Zhangjiakou Area in northern Hebei Plateau and in Cangzhou Area in coastal areas. The gale had the highest frequency in spring; wind disaster events happened in various regions of Hebei Province, but in light degree, which should be in the charge of county supervision institutions. Using wind disaster risk assessment model with the combination of disaster-inducing factors and hazard bearing body, it showed that there were 14 very severe wind risk areas in Hebei Province. In conclusion, more parameters of the hazard affected body should be added to the risk evaluation or the weight of the affected body ration should be increased.
